Channels2 (accelerometer / velocity / displacement)
Frequency range10 Hz-10 kHz
FFT resolution3200 lines
Acceleration0.1-500 m/s²
Overview
Covers the three jobs a reliability team actually does on a route: overall severity to ISO 10816, an FFT to find the fault frequency, and a two-plane balance to fix it. The accelerometer mounts with a stud or a magnet, and the route data exports as CSV.
Key features
- Two channels: accelerometer, velocity or displacement
- Frequency range 10 Hz-10 kHz, 3200-line FFT
- ISO 10816 severity bands with colour grading
- Two-plane field balancing with vector display
- Bearing fault frequencies (BPFO / BPFI / BSF / FTF)
- 8 GB storage, CSV export, 12 h battery, IP65
